:-) 12V found its way onto the ground line. I had a blond moment. My description on this is no where near as spectacular as the the units dying breath. What amazed me was that I contacted them for a the cost of a replacement, and they sent it gratis. BTW I checked out the other one someone brought up here and they are very similar except that the Salae unit doesn't need specific clock connections, instead capturing the timing of all transistions and then post processing in SW. It does have smarter trigger options.

I have their 8 channel version, and it comes with small micro clips as found on Tek logic analysers and the likes. Not only is the product easy to use, there support and backup is unbelievably good. I blew mine up and when I told them how I did it they FedEx'ed a replacement free of charge because they reckoned it shouldn't have failed under those conditions. The interface is a little quirky when compared to standard windoze applications, but it's easy to get used to and it does everything I believed it could plus more. Occasionally I think I want to do xyz. and I go through the options and low and behold it can do it. It has a developers API that allows you to develop instruction decoding although I haven't tried that yet. Anyhow, just brilliant. I've had 2 people so far see what I can do with it and they've ordered one straight away. I can't speak highly enough of the product or the company's support

@AKPN and MAX: Probes and accessories are as essential as LA itself. What kind of probes/accessories are provided with this LA? If they include good kit with it, it may be worth money. If not, price almost becomes double.

There is a logic analyzer I have been using for several years with 34 channels and up to 500 MHz acquisition. $389

Google "logicport"

I have not found anything that competes with it. It uses an FPGA and has a very good user interface, USB connection. Timing accuracy for comparing across channels is very good and a wide range of switching thresholds are easy to set.

@BobGroh: My first thought was '....yeah, I bet that sucker costs a bit..' The answer is: Nope. It is a bit south of $300. That is both a nice price point and a lot of capability.

I just checked their website -- as you say, the "Logic16" (with 16 channels) is $299, which is a pretty decent price. But the original "Logic" (with 8 channels) also looks to be very tasty at only $149.

Of course I say "only" ... but I don'tt have a spare $149 lying around at the moment ... on the other hand, I'm going to be needing a logic analyzer for a forthcoming project ... hmmm...
